1. Use the ruler to measure one inch of the short side of the paper and cut it. Set this part aside as this will be used as the handle for the lantern.
2. Fold the paper in half along its length. Draw a line one inch from the edges of the longer side of the paper.
3. Now cut along the marked lines and unfold the paper. Re-fold the paper in the opposite direction to hide the markings.
4. Now roll the paper so that the two ends match the two long edges of the paper and staple them together.
